【 摘 要 】

We are developing an ab initio numerical method to compute molecular single and double ionization processes induced by intense laser pulses. We present our first time-dependent simulations in the H2+molecular ion including both electronic and nuclear degrees of freedom. We compare different methods for the extraction of excitation and ionization probabilities from the numerical time-dependent wave function, which will be applied to more complex targets in the future.
